Revegetation of Cascade Pass

THE WILD CASCADES Voluntee r Work Pa rty — en route to Cascade Pass, NCNP, WA. The Millers, Bill Lester and helpers. 'William Lester Photo The Greening of the North Cascades Joseph W. Miller With all our concerns in Washington State about population pressures, pollution, transportation, oil spills, loss of ancient forests and endangered species et cetera et cetera, it is refreshing to be able to report that North Cascades National Park is a greener, less impacted place than when Congress passed the enabling legislation in 1968. Since my wife, Margaret, and I played some part in this felicitous outcome, I have been asked to tell briefly how it came about. The first superintendent, Roger Contor, was a man of boundless energy who quickly made it his business to learn as much as possible about the assets and problems of the superlative piece of real estate he had inherited from the Forest Service. One of his first actions in the park's first summer was to contract with E>r. Dale Thomburgh of Humboldt State University to survey human impact at Cascade Pass and make recommendations for its possible restoration. Thomburgh's report came out in January, 1970, and included detailed maps of the 42 worn camping areas and the numerous social trails in the Pass vicinity, a description and map of the plant communities, and some suggestions for revegetating the area. 15 (KTOBKR 1991 Contor promptly closed Cascade Pass (and the other subalpine passes) to camping and fires at the beginning of the 1970 season. He had previously enlisted the Millers in 1969 as volunteer researchers to fill some other blanks in the park's data bank — a survey of what existed in the soon-to-be flooded (everyone thought) Big Beaver Valley, and a comparison of the western redcedar plant communities in four of the park's low level valleys. Knowing that, as long-time dirt gardeners, we would probably snap at the bait, he sent us a copy of Thomburgh's report and invited us to a staff meeting at Cascade Pass in August, 1970. The meeting, which included a number of desk-bound staff members who were seeing Cascade Pass for the first time, was held on one of the worst beat-up campsites just over the Pass. We had first seen the Pass in the early 60's before the Forest Service extended the Cascade River road and built the parking lot and the new trail with the jillion switchbacks. We considered Cascade Pass to be a subalpine slum even then and went on the contribute to the degradation of Sahale Arm by camping on the heather. The Pass was in much worse shape now, and the assembled brass agonized over ways to halt its decline without any money to spend on it. The upshot of it was that increased ranger patrols and signing would try to halt the illegal camping, and the Millers, invincible in our ignorance of high altitude growing conditions, would try to revegetate it. The only caveat was that we would use only native plants in our efforts. We made five visits to the Pass during August and September that year, driving from our home in Bellevue and camping at the Mineral Park Forest Camp. Acting on suggestions from Thomburgh and George Douglas, a doctoral candidate from the U. W., who had studied the plant communities of the park, we collected ripe seeds of nine different plant species in the area and planted specific numbers of seeds in half-meter square test plots on aspects facing each of the four compass directions. All very scientific! We also dug and planted one of the big bare campsites with 140 10cm circular plugs of partridge foot, Luetkea pectinata, with a miserable plugging device given us by the Park Service. Finally, we let our dirt gardening bias take over, and we dug up four of the bare campsites and planted them with a duke's mixture of every kind of seed we could find in the area. Early snow caught us before we finished our labors. During the winter months we hit the books and journals in the Science and Forestry Libraries at the U Dub trying to find some 16 THE WILD CASCADES helpful information on subalpine revegetation. There was an abundance of detailed studies of human impact and trampling - things like how many steps with hiking boots it takes to make a social trail across a heather meadow, but zilch on the grunt work of trying to replant already worn areas. About all we could find were some reports of seeding high altitude mine spoils and road cuts with commercial seed mixtures, and this was of no help. We were pretty much on our own, and anything we tried would be frankly experimental. In 1971, in between continuing our survey work in Big Beaver and beginning a wildfire plant succession study on three of the 1970 burns, we made five more trips to Cascade Pass. Weather conditions had been hot and dry, and there was little evidence of germination on the lest plots. Only 52 of the 140 plugs of vegetation transplanted the year before had survived. We toted a 4 cubic foot bag of peat moss (in bags) to the Pass, dug up the planting areas with a spading fork, replanted the test plots with new seed and planted 59 more plugs. We also collected cuttings of several species to try propagating them in our little greenhouse at home. In early August of 1972 we received a short and shocking letter from the new superintendent who had replaced Roger Contor when the latter moved on to higher things. We were instructed to discontinue any further plantings at Cascade Pass until "Firm Natural Science Proposals (Study Plans) were formulated." Questioning of our contacts in the park disclosed that a graduate student at the U Dub had submitted a thesis proposal in which he would make a five-year study of "revegetation processes along lines of ecological parameters" and would "evaluate quantitatively as to density, cover and frequency of successes relative to prepared and unprepared substrates." This apparently sounded more dignified to the park people than our pragmatic, horticultural approach to revegetation. We appealed to the Regional Scientist, pointing out that laboratory conditions do not prevail at Cascade Pass and that carefully controlled test sites are like as not to be destroyed by the thoughtless minority of campers who were continuing to sneak up to the Pass between ranger patrols. Probably because we constituted cheap (free) labor and anyone else would have to be paid, we finally received clearance to go ahead, but the 1972 planting season was lost. 17 OCTOBER 1991 We had by now decided that direct seeding in any but the most favorable moist sites was hopeless and that transplanting plugs of vegetation, while fairly successful, was precluded at the Pass by the very limited availability of undamaged meadow vegetation. The cuttings and divisions of plants we had taken down in 1971 had thrived in our unhealed greenhouse, and in 1973 and 1974 we concentrated on carrying back to the Pass rooted plants grown down below. In September, 1974, we enlisted the aid of friends who helped us as volunteer Sherpas in carrying 340 pounds of plants to the Pass and planting them. When we evaluated the plantings in early August, 1975 and found better than 85% survival despite the six weeks of dry weather after we had put them in the ground, we knew we had the answer. Skagit District was convinced, too, and built us a 12' x 4' coldframe from plans we submitted, and we stocked it in the fall of 1975 from cuttings and divisions brought down from the Pass. In August, 1976, the flats of rooted plant material were dumped out into plastic bags and carried up to Cascade Pass by a group of the backcountry staff to whom we were supposed to demonstrate planting techniques. It was one of those more miserable days when the cold, wet wind howls through the Pass and almost blows the plants out of the ground. We all had to cache the bags and retreat to Marblemount before hypothermia set in. A small, plastic-covered greenhouse was built later that year which we stocked with cuttings. Unfortunately, someone in the District neglected to water it during the winter, and another year was lost. So the revegetation project rocked along, alternating between benign neglect and official indifference until early 1978 when William Lester, the new backcountry ranger, came on duty from his previous post at Olympic. A human dynamo. Bill quickly reconnoitered every part of the Skagit District backcountry and determined that restoration of those areas degraded by human impact was both essential and practical. Kathy Lester, Bill's wife and an equally energetic person, had previously worked in a commercial greenhouse and possessed the proverbial green thumb. She volunteered to take charge of the little Marblemount greenhouse and began to produce plants for Cascade Pass in quantity. While waiting for the fall planting season in the subalpine. Bill began a full scale revegetation program in the park's forest zone. Without a budget for restoration work, he used Student Conservation Association volunteers to develop comprehensive plans for repairing the many old scars along the trails and then carry out the work. The 18 THE WILD CASCADES seasonal backcountry techs were trained in revegetation techniques and in teaching minimum impact camping to visitors. During 1980, using YACC labor and mainly local materials. Bill designed and built a large propagating greenhouse that was a model of its kind and the envy of other parks in the Northwest.
